How it works
The digits are read as text, not as a floating-point value, so every figure up to 999,999,999,999,999 converts exactly. The international reading splits the integer into groups of three and names them thousand, million, billion and trillion, using the short scale in which a billion is a thousand million. The Indian reading takes the last three digits, then groups of two for thousand and lakh, and counts crores above that; past 99 crore the crore count is itself read in lakhs, so 10^12 becomes 'one lakh crore'. Following the US Government Publishing Office style, numbers from twenty-one to ninety-nine take a hyphen and no 'and' is inserted ('one hundred twenty-one'); a toggle adds the British and Indian 'and'. Without currency, decimals are read digit by digit after 'point'. With currency, two decimals become the minor unit, singulars are respected ('one dollar and one cent'), rupee amounts use the 'Rupees ... and ... Paise' order common on Indian cheques, and an optional 'only' closes the line.
Method
- International: groups of 3 digits - thousand (10^3), million (10^6), billion (10^9), trillion (10^12)
- Indian: hundreds, then thousand (10^3), lakh (10^5), crore (10^7); crore counts above 99 read recursively
- 21-99 hyphenated (twenty-one); 'and' after hundred only in British/Indian style
- Currency: up to 2 decimals as paise / cents / pence
Worked examples
Both systems at once
Inputs: 1234567.89
Result: International: one million two hundred thirty-four thousand five hundred sixty-seven point eight nine; Indian: twelve lakh thirty-four thousand five hundred sixty-seven point eight nine
Without currency, decimals are read digit by digit.
An Indian cheque
Inputs: 250000.75, Rupees and paise, Title Case, only
Result: Rupees Two Lakh Fifty Thousand and Seventy-Five Paise Only
The international line reads Rupees Two Hundred Fifty Thousand and Seventy-Five Paise Only.
Limitations
- English only; Hindi or other languages and the traditional arab/kharab names are not produced.
- At most two decimal places; ordinal forms (twenty-first) and fractions in words (three-quarters) are not generated.
- Currency wording covers rupees, dollars, pounds and euros; other currencies need manual editing.
Where publishers use it
- Cheque-writing guides and bank help pages
- Invoice and quotation templates that need the total in words
- English-language lessons on reading large numbers aloud
- Indian accounting and GST blogs that work in lakh and crore
- Legal drafting pages where sums are written in both figures and words
Questions
How do I write 12,34,567 in words?
Twelve lakh thirty-four thousand five hundred sixty-seven. In the international system the same number, written 1,234,567, is one million two hundred thirty-four thousand five hundred sixty-seven.
How many lakh make a crore, and how much is a crore in millions?
100 lakh make one crore. A lakh is 100,000 and a crore is 10,000,000, so one crore equals ten million and 1 million equals 10 lakh.
Should I write 'one hundred and twenty-one' or 'one hundred twenty-one'?
Both are correct in different traditions. US style, including the GPO Style Manual, omits 'and'; British and Indian usage includes it. Use the toggle to pick.
How do I write 1,250.50 on a cheque in India?
Rupees one thousand two hundred fifty and fifty paise only. Choose 'Rupees and paise', turn on 'only' and Title Case for 'Rupees One Thousand Two Hundred Fifty and Fifty Paise Only'.
Is a billion a thousand million or a million million?
Modern English uses a thousand million (10^9), the short scale. The older British long scale used a million million; the widget follows the short scale.
What is the largest number it converts?
999,999,999,999,999 - nine hundred ninety-nine trillion and the rest - with up to two decimal places.
